I just got one brand new and cheaper off of Amazon.com with free shipping. the material itself is lighjtweight and durable.... but you want to use it as a tarp/rain fly... not a groundcloth. it's pretty durable but too likely to rip if it's on the ground.
it's very good size... but it is meant to be used with a hammock or as an instant shelter.
the reflective side..... is almost white. not silvery at all
I carried one of these bad boys for over six years, and never had a single complaint about it. sadly i lost it last summer. it functions amazingly, and the scissors are more like tin snips! the blade holds it's sharpness very well, and the wire cutters are strong enough to go through a coin! no compliants to be had here, or by anyone else I've ever met who carries one!
